Laparoscopic Nephroureterectomy with Heminephrectomy for Urothelial Carcinoma of the Upper Renal Pelvis on the Left Side of the Horseshoe Kidney

Abstract

A 70-year-old male was diagnosed with urothelial carcinoma of the upper renal pelvis on the left side of the horseshoe kidney. Preoperative thin-slice contrast-enhanced CT with three-dimensional reconstruction of the images revealed that two arteries arising from the aorta supplied the left moiety of the horseshoe kidney. He underwent laparoscopic transperitoneal nephroureterectomy with heminephrectomy on the left side of the horseshoe kidney visualized by indocyanine green fluorescence system. The histopathological findings of the renal pelvic tumor revealed invasive urothelial carcinoma with squamous differentiation, high grade, and pT3.

Pure laparoscopic radical nephroureterectomy for complicated renal pelvis carcinoma combined with horseshoe kidney: A case report and literature review

“…In addition, to avoid the cancer cells implanted along the right ureter, we ligated the upper ureter with Hem-o-lok during the procedure, which is especially worth noting. Comprehensive preoperative preparations and correct surgical planes are necessary for this kind of patient; the three-dimensional analyzer of the images and intraoperative indocyanine green (ICG) fluorescence system may help us further confirm the blood supply ( 7 ), which may be useful in nephron preservation without compromising oncological outcomes. We suggest that the use of laparoscopic HSK surgery will cause minimal surgical insult to patients and effectively improve the patient’s quality of life.…”
